I have heard of these but at the time my books had no ratings, and I hadn't gvien them much thought since then. Now that you have brooched the subject again I think it might be time that I consider going back to one of these and maybe look into promoting my books. I think I have only one that has like three and a half stars which doesn't qualify but the other three have four stars at least so these could qualfy, I will have to check. Also, is there a fee to use these to promote your book? I guess I would understand if there was I know of one website that I am considering using that has a fee of around thirty dollars for a year of promoting the book to the blog readers. I guess this is a good deal since the exposure is for an entire year and I do like the blogs layout. Its called the sleepy book worm for anyone else who is interested in checking it out.
